Ideally, the gas sampling hose temperature should be 20-30 °C above
the dew-point temperature.
When HYGROPHIL H 4230 is delivered, the gas sampling hose temper-
ature is set to 120 °C.
If you do not have any information with regard to the range in which the
humidity of the gas to be measured lies, start the measurements with the
default value.
Observe the dew-point temperature during the measurements.
If the measured dew-point temperatures lie between 60 and 90 °C, no
change needs to be made to the gas sampling hose temperature.
If the dew-point temperature is regularly over 90 °C, the gas sampling
hose temperature must be increased to 130 ... 140 °C.
If the dew-point temperature is below 60 °C, you must reduce the gas
sampling hose temperature in order to prevent display errors.
The following diagram is intended to help you find the most suitable gas
sampling hose temperature.
